available on the job site, inform related
utilities providers and mark the area. Be
careful not to cut or damage any lines.

Prevent any unauthorized personnel from
entering the job site. Designate a signal
man and fence the job site when operating
your machine on a highway.

zen ground. Increase of ambient tempera-
ture may result in soft and slippery ground.

water fl ow before operation.
2.3.24 Operation on soft ground
●
Avoid traveling or operating your machine
near cliffs, road shoulders or trenches. The
soft ground plus machine weight and vibra-
tion can cause your machine to sink or tip
over. The ground may become even softer
after heavy rain, explosion or earthquake.
●
When operating on a dam or near an exca-
vated ditch, vibration and machine weight
may trigger a landslide. Before operation,
take protective measures to prevent your
machine from tipping over or falling.
